    Collecting Data From Solar Panel Setup

    After having setup the solar panel on our terrace, I wanted some data. Specifically I wanted to know the panel output over the course of the day and how much energy savings we are enjoying. The solar management unit (SMU) gives some details about the instantaneous power output and energy savings. But for some reason I felt the numbers look a bit too optimistic. Moreover I could not get more granular data from it. I guess it has more to do with not invented here syndrome. Either way I decided to hook up some sensors myself to gather all the data I'd like from it.

    Solar Panel Performance And Energy Savings

    Alright, so I got my solar panels and solar management unit setup all done. Now for the results. According to the spec sheet of my solar panel, it should be able to generate peak output of 320 W. And it certainly did. In fact on some rare occasions it actually produced more than the rated capacity! I was really surprised that something can outperform a spec sheet. From the spec sheet, the panel is supposed to produce 320 W with an irradiance of 1000 W/m2 under standard test conditions (STC). Whatever that means.

    Wiring Solar Panels, Solar Management Unit and UPS

    If you have been following my solar panel project story, you know what parts I needed to get started on the project. I ordered them from Amazon and they started arriving at my door step in due course. Once I had everything delivered, we carried the panel to the roof. I made some basic electrical measurements to make sure everything was in order. Next we ran the solar cables from the terrace to the ground floor. According to the manual, the wiring has to be done in a certain order. I will explain the connections in that order.

    DIY Solar Panel Project - The Ingredients

    As I mentioned in the previous post, I decided to go with a hybrid charge controller solution for my solar panel setup. What that basically means is that I will need to buy some solar panels and a hybrid charge controller, since I have a UPS and batteries. I will then have to connect them all together. I wanted to start with something simple, so I decided to just buy one solar panel. At the same time I was intending to build it in such a way that it can be extensible to 3 panels in the future. The goal has always been to have a 1 KW setup.

    Solar Panel Project - Do It Yourself

    I was finally ready to install solar panels. After having made all the calculations, I arrived at the fact that I could get the return on investment in 5 years. But I had an even better idea. I decided do build it myself. What better way to learn about solar power except by doing it yourself! I always prefer to do things myself rather than letting some one else do the job for me. My work will be subpar at best, but it not only gives me a great opportunity to learn something new, but is also a lot of fun.
